How your aircraft can benefit from Tuneable Antennas

Posted on 2 February, 2022 by Hana Ellis

Chelton has been pushing the boundaries since the early days...

...and in the 1960s it was unrelenting in creating an ‘all-singing, all-dancing’ antenna. The result? The world’s first radio-silent tuneable antenna.

Up until Chelton’s pioneering solution, tuneable antennas needed a burst of transmission to be able to re-tune, which in turn gave away an aircraft’s position and left its communication system vulnerable to jamming attacks.

A tuneable antenna is a simple concept; it contains electronics that allow the antenna to be ‘tuned’ to a particular frequency range on demand. This provides up to 15dB better gain at the lower end of the Very High Frequency (VHF) band compared to a passive blade antenna of equivalent size.

But how can tuneable antennas perform as well, if not better, than passive antennas? Are they ideal for particular frequencies? Are there are size or space limitations?
